These subs are great!! Only reason I am selling is the same as the other subs I have for sale -- I ordered a stealthbox so I have no need for them. These subs are pretty hard to find..... only place I have seen them that actually has them in stock is woofersetc.com and they want $200/each for them. They would be perfect in a Supercrew Sound dual 10" sub box. The specs are hard to find; they have a 5.75" mounting depth, are dual 2 ohm subs, and handle 400 watts RMS. That's about all I know off the top of my head. I had them in a common chamber enclosure with a total airspace 1.2 ft^3 and they sounded great in it so I know they would sound good in the F150 dual box. Looking to get $275 shipped for the pair.
